� ISODD is an information function—an Excel function that provides information about a cell’s contents. The ISODD function returns the value TRUE whenever it evaluates a cell with an odd number.

� Information functions are often nested in IF functions. For example, the ISODD function can be nested in an IF function to display a custom message when a value is odd or even.

� The ISERROR function evaluates a cell to determine whether the cell contains an error message. If the cell contains an error message, a value of TRUE is returned.
